Embodiment
Fig. 2 is the perspective view of cooking device according to an embodiment of the invention.As shown in the figure, heater 20 comprises: be used for surpass whole radiant energy 65% in the infrared spectral range of wave-length coverage greater than 1.35 μ m radiative Halogen lamp LED 20-2; Be installed in the reflecting disc 20-1 on Halogen lamp LED 20-2 top, it is suitable for the light from Halogen lamp LED 20-2 emission is reflexed to target object; Be installed in the mesh unit 20-3 with a plurality of through holes of Halogen lamp LED 20-2 bottom, therefore be used for by light of launching from Halogen lamp LED 20-2 and the light that reflects from reflecting disc 20-1; Be installed in the filter 20-4 of 20-3 bottom, mesh unit, therefore be used for protecting Halogen lamp LED 20-2 and direct by light from mesh unit 20-3 emission; And be used for the cooking room 21 of cooked food.To be elaborated to it with reference to figure 3.
Fig. 3 is the sectional view of heater 20 parts of enlarged drawing 2.
At first, Halogen lamp LED 20-2 launches light to surpass 65% of whole radiant energy in the infrared spectral range of wave-length coverage greater than 1.35 μ m.From Halogen lamp LED 20-2 radiation emitted can wavelength along with as the temperature of the filament (tungsten) of thermal source and difference.
Here, use at the cooking device that is used for cooked food under the situation of Halogen lamp LED 20-2, can allow to launch light with the wavelength that is suitable for cooked food.
On the other hand, under the situation of using Halogen lamp LED 20-2 to be used to throw light on, can allow temperature (colour temperature) by increasing filament from the most radiant energy of VISIBLE LIGHT EMISSION.
Therefore, Halogen lamp LED 20-2 has the colour temperature that is higher than 2400K, so that can launch the light with the wavelength that is suitable for cooked food.
Can there be various methods that the colour temperature of Halogen lamp LED 20-2 is adjusted to 2400K.For example, by when making the filament of Halogen lamp LED 20-2, adjust energy resource density according to the diameter of the length of lamp, heat ray, resistance or the like, thereby Halogen lamp LED 20-2 is designed to have the saturation temperature of 2400K.Then, when power supply is supplied to Halogen lamp LED 20-2, in a single day the filament of Halogen lamp LED 20-2 reaches according to the energy resource density predetermined temperature of institute (2400K) that designs above will become saturation condition, and no longer increase afterwards.
If colour temperature is too low, the strength of the radiant energy of Halogen lamp LED 20-2 diminishes.Therefore, suitable colour temperature minimum is 1600K, and 2200K preferably.
Then, reflecting disc 20-1 is installed in the top of each Halogen lamp LED 20-2, gathering cooking room 21 from the light of Halogen lamp LED 20-2 emission.Just, it is used for the light from Halogen lamp LED 20-2 emission is reflexed to cooking room 21, so just can not be transmitted into the outside.
In addition, reflecting disc 20-1 is coated with stainless steel or aluminium, and they all are metal materials, because it must reflect the light that produces from Halogen lamp LED 20-2, rather than absorbs it, and the energy that produces from Halogen lamp LED 20-2 does not just have loss like this.
Mesh unit 20-3 is installed in the bottom of Halogen lamp LED 20-2, and has a plurality of through holes, incides in the cooking room 21 from the light of Halogen lamp LED 20-2 emission and the luminous energy that reflects from reflecting disc 20-1 like this.
Filter 20-4 is installed in the bottom of mesh unit 20-3, with protection Halogen lamp LED 20-2 with make light incide cooking room 21 in the cooking device by mesh unit 20-3.Here, filter 20-4 is made by pottery or glass ceramic material.
After this, incident light impacts the target object (food) in the cooking room 21 that enters in the cooking device.
Fig. 4 shows according to the figure of light wavelength with respect to the reflectivity of different food products.As shown in the figure, food absorbs the energy in the infrared spectral range usually, and the energy in the reflect visible light zone.
Therefore, owing to the high-absorbility that infrared ray is applied to food, can flash-cook food.
Fig. 5 shows according to light wavelength with respect to stainless steel material (ST430, the figure of the reflectivity of reflecting disc ST304).As shown in the figure, can know with the visible region and compare that the reflectivity in the infrared spectral range is higher.
Fig. 6 shows the curve chart of basis from the spectral distribution of the colour temperature of the light of Halogen lamp LED 20-2 emission.Just, how different along with the colour temperature of light the spectral distribution of the light of launching in order to find is, detected the spectral distribution according to the colour temperature of the light of launching from Halogen lamp LED 20-2 for displaying.Here, " spectrum " means that light is divided into different colour bands according to the wavelength difference.
As shown in the figure,, can know, represent the peak point of maximum intensity to move to long wavelength's scope along with the colour temperature step-down according to top spectral distribution.The area of spectral distribution curve lower part is represented radiative energy separately.In other words, can know that the energy quantitative change in long wavelength's scope is big.
Table 1 has been showed according to the ratio of wavelength region may with respect to the radiant energy of top colour temperature 2300K and 2400K.
[table 1]
| | 2300K | 2400K | ||
| Ratio (%) according to the radiant energy of wavelength region may | 0.4～0.7μm | 2.11％ | 2.8％ | |
| 1.0 | 12％ | 14％ | ||
| 0.4～1.35μm | 29.6％ | 33％ | ||
| 1.35μm～∞ | 70.4％ | 67％ | ||
Above the wave-length coverage of 0.4～0.7 μ m be the visible region, above the wave-length coverage of 1.0 μ m be the intermediate range of near infrared range.0.4 the wave-length coverage of～1.35 μ m is visible region and near infrared range.In addition, the wave-length coverage above 1.35 μ m is an infrared spectral range.
From table 1, can see because bigger at the radiant energy of the infrared spectral range of the colour temperature of 2300K (being lower than 2400K), in order to increase the radiant energy in the infrared spectral range, use be the light of lower color temperature regions.
In addition,,, can regulate the cooking time selectively, particularly can flash-cook need the food of flash-cook according to food type by the radiative wave-length coverage of the top differentiation of introducing.
As mentioned above, in the present invention, because Halogen lamp LED 20-2 is transmitted into the light in the infrared spectral range on the food, food absorbs the light in the infrared spectral range of being launched well, thus cooked food at short notice.
In addition, the reflecting disc of non-corrosive material allows the light in the infrared spectral range to accumulate on the food, thereby reduces the cooking time in large quantities.
Because under the situation that does not deviate from spirit of the present invention and inner characteristic, the present invention can be presented as several forms, unless therefore be to be understood that and specialize, the details that the foregoing description is not subjected to illustrate previously limits, and broad interpretation in its spirit and scope that should in accessory claim, define, and therefore satisfy the purpose of invention and all changes of scope and the equivalent of modification or these purposes and scope and all comprised by claims.
